First sun exposures: how to properly prepare your skin?

The return of the sun makes us want to be out in the sun, to feel the warmth on our skin and to enjoy the beautiful weather. But after several months spent sheltered from natural light, our skin is not ready to face sudden exposure .

Without preparation, initial sun exposure can lead to sunburn, inflammation , or invisible damage from UV rays . Here's why it's essential to gradually acclimate your skin to the sun , and how to do it wisely.

Why is skin more vulnerable in spring?

During autumn and winter, the skin is less exposed to UV rays :

• Natural light is weaker and less frequent.

• We're staying indoors more.

• Covering clothing reduces exposure.

• Melanin production slows down , making the skin lighter… and more fragile.

In spring, skin is often drier, thinner, and more sensitive . Sudden exposure acts as an aggression: the skin barrier is not ready, the microbiome is disrupted, and the skin reacts more violently to UV rays.

Gradual exposure: the key to healthy adaptation

When it comes to sun exposure, moderation and regularity are the best allies for successful exposure.

Best practices for first-time exhibitions:

• Start with 10 to 15 minutes for the first few days.

• Avoid peak hours : between 11am and 4pm.

• Gradually expose sensitive areas : face, décolletage, shoulders.

• Don't wait until you turn red: redness is already cellular damage .

Gentle, repeated exposure allows the skin to:

• Reactivate its production of melanin , the natural protective pigment.

• Strengthening one's internal defenses against aggression.

• Stimulate the synthesis of vitamin D , which is essential for proper immune function.

Preparing your skin before sun exposure

Adapting to the sun begins well before you even hit the beach. Here are the three pillars of skin that is more tolerant and resilient to UV rays.

1. Skin hydration

Well-hydrated skin:

• Maintains a functional lipid barrier.

• It is less prone to peeling or inflammation.

• It offers better resistance to the penetration of free radicals.

In addition to drinking water, topical treatments rich in hyaluronic acid , film-forming polysaccharides or ceramides are preferred.

2. Antioxidants

Antioxidants neutralize free radicals generated by UV rays , thus limiting inflammation and premature aging .

3. Strengthening of the skin barrier and microbiome

Preparing the skin also means supporting its natural ecosystem :

• A stable hydrolipidic film limits dehydration.

• A balanced microbiome protects against external aggressions.

• Prebiotics such as inulin enhance this stability.

Why sun exposure isn't always dangerous

In the culture of "total protection," we sometimes forget that the sun, in the right dose , also provides benefits:

• It activates vitamin D , which is crucial for immunity, bones, and hormonal balance.

• It stimulates blood circulation and serotonin synthesis , contributing to mental well-being.

• It allows the skin to gradually regain its natural defense mechanisms .

But to achieve this, it is necessary to accompany this exposure with skincare that supports the skin , rather than enclosing it under an impermeable filter.

Biomimetic photoprotection: a gentle solution for initial exposures

Unlike conventional sunscreens that block UV rays, biomimetic photoprotection offers an approach that is more respectful of the skin's biological functioning .

Its advantages:

• It allows some UVB rays to pass through , enabling the skin to adapt and produce vitamin D.

• It neutralizes the harmful downstream effects , including oxidative stress and inflammation.

• It does not suffocate the skin , nor its microbiome.

MONO Skincare's Sun Defense gently supports the skin

Sun Defense is a 100% natural mist, without UV filters, designed to strengthen the skin's tolerance to the sun. Ideal for initial sun exposure , it acts as a skin defense booster , thanks to a combination of biomimetic active ingredients:

• Ectoin : protects cellular DNA, reduces inflammatory reactions.

• Beta-glucan : strengthens the skin barrier and soothes sensitivities.

• Schizophyllan : fungal antioxidant that stimulates natural defenses.

• Inulin : a plant-based prebiotic that supports the microbiome.

• Patented complex : hydrates, protects and stimulates cellular functions.

Applied daily in the spring, Sun Defense prepares the skin for more natural and better tolerated sun exposure , without interfering with its vital functions.
